Simple, challenging, and full of fun. For your first game, it's is impressive. The game is random and there is no rhythm you can get used to it, and that makes it hard but I managed to finish it after few tries. I have few notes about the game:
- First, the hitbox between the player and the ghost, the player have a small hitbox for attacking, but a big one for taking hits, and that makes the player feel frustrated when he thinks that he clicks at the right time but the game has a different answer, and specifically with the fast ghosts. Try to make the player hitbox smaller and the flashlight hitbox larger.
- The randomness in the game makes it hard but also unbalanced. In my case, I got a lot of fast ghosts in the beginning, but in the last 15 seconds, I didn't get any. It would be better to make the speed increase (start slow and then go fast) by keeping the randomness but making a range that keeps increasing.
- My last point is about animation, I don't know if the player is the one who's moving toward the ghosts or the ghosts to the player (I think you make it both towards each other), but the player movement feels like he is just setting on a chair and playing with his legs. If you planning that the player moves towards the ghosts it will be better to just adjust its animation speed to match the speed of the ghosts.
